……这可能是早年Pascal盛行的时候考排序的吧居然还是Glod……

#include<iostream>
#include<cstdio>
#include<algorithm>
using namespace std;
const int N=100005;
int n,a[N];
int read()
{
    int r=0,f=1;
    char p=getchar();
    while(p>‘9‘||p<‘0‘)
    {
        if(p==‘-‘)
            f=-1;
        p=getchar();
    }
    while(p>=‘0‘&&p<=‘9‘)
    {
        r=r*10+p-48;
        p=getchar();
    }
    return r*f;
}
int main()
{
    n=read();
    for(int i=1;i<=n;i++)
        a[i]=read();
    sort(a+1,a+1+n);
    printf("%d\n",a[(1+n)>>1]);
    return 0;
}
